我有一个facebook iframe标签，上面有一些youtube视频，这些视频直接来自youtube api提供的json响应。
当您选择缩略图时，视频会嵌入选项卡的顶部，然后可以播放。
嵌入视频下方还显示标题，说明，视图和分享按钮。
目前，每个视频的共享信息都是相同的，我正绞尽脑汁地为每个视频自定义它，即使这意味着要进行ajax调用。
以下是相关代码：
$(document).ready(function() {
$('.share_button').live('click', function(e){
// fade out video to stop it conflicting with dialogue box
$('#player').fadeOut('slow');
e.preventDefault();
FB.ui(
{
method: 'feed',
name: 'generic name',
link: 'generic link',
picture: 'generic image',
caption: 'generic caption',
description: 'generic description'
},
function(response) {
// fade video back in once the dialogue box is closed
$('#player').show('slow');
});
});
我的标签的完整代码是：
$url = 'http://gdata.youtube.com/feeds/api/videos?max-results=20&alt=jsonc&orderby=published&format=5&safeSearch=none&author=CHANNELID&v=2';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_REFERER, $url);
$body = curl_exec($ch);
curl_close($ch);
$data = json_decode($body, true);

};
(function() {
var e = document.createElement('script');
e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js';
e.async = true;
document.getElementById('fb-root').appendChild(e);

如果有什么不清楚，请告诉我，我会尝试更好地解释它。

如果您正在共享粉丝页面上的标签链接，则无法自定义在Facebook上显示为描述的文本。他们默认使用页面的描述和PAGE_NAME | TAB_TITLE作为标题。
但是有一个解决方法：
您只需在服务器上共享一个URL，您可以在其中控制Open Graph标记并根据已共享的视频显示它们。如果用户现在单击此类共享链接，您只需将其重定向到Facebook页面上的选项卡即可。
如果您还需要某种方式深度链接到共享视频，您可以使用URL参数“app_data”将其传递到您应用的iFrame。
